The purpose of this study is to identify pre-elderly's housing mobility related characteristics (reasons for moving, change of personal life after move, housing attachment, and plan to future move) and to examine the associations between their socio-demographic characteristics and housing characteristics, and their housing mobility related characteristics. A total of 200 usable data were collected through personal survey using a questionnaire developed by the researcher. Samples were selected in Seoul and new towns in the capital area and a survey conducted from February, 2014 to December, 2014. For the analyses, descriptive statistics, factor analysis, t-test and ANOVA were used. The most frequently mentioned reasons for moving were 'a good place for nature and retirement life'. Age, education level, liiving expenses, locaion, tenure status, and housing size were the variables to show significant difference to reasons for moving. Respondents experienced positive personal life changes after moving, especially, 'physical health' and outgoing activity'. Respondents who moved to a new town was more positively changed. Personal life changes was the most important variable associated with 3 factors of housing attachment. Location, tenure status, housing size were the major variables to show differences to housing attaachment. Also, personal life changes after moving and housing attachment were the important variables affecting a plan to future move. In other words, the respondents who do not plan to future move showed higher positive life change and strong housing attachment.

For assessment of U-Eco City technologies, more concrete definition of those technologies are required. However, almost researches defined technologies as conceptually and even cannot include all of them. In this sense, the purpose of this study is to deduct assessing items for specifying applying priority of U-Eco City technologies. We performed the research by 3 steps. Firstly, we deduct assessing items of the technologies by researching their advance process. After then, we compensate the defect of those items through documentary research and made a periodic table about core technologies that can be useful for deducting long-term items. The assessing items what are deducted as a result of this study can be applied to the selection of technology, and will be useful to construct more objective and systematized U-Eco City. Furthermore, if assessment frame about technologies and services is developed from this research, it gives to us probability that standardized process of U-Eco City construction can be established.

A number of BTL projects for educational facilities have been augmented because of the increase of newtown development and deflationary policy of class size for learning efficiency. As the operation and maintenance costs rapidly increase, the budget for operation and maintenance is expected to be short. Therefore the asset management maximizing asset value is required to clarify the budget plan and distribution and provide a qualitatively high service. The main objective of this research is to establish asset valuation process in educational facilities delivered by BTL project. In order to meet the research objective, the asset valuation process is established by literature reviews, expert advice, and lessons learned from the developed countries. The developed process includes depreciation by internal accounting law, the core element of valuation, and asset valuation process. The results of the research will be help to offer the qualitatively high service and explain the standard of budget plan. It will assist commencing the asset management system.

The amount of soil cutting, transported, and filing up the soil in the project area is considered to change the volume depending on the condition of the soil; the volume change rate of the soil is calculated by collecting undisturbed samples below 1 m to 2.0 m above the surface through test pits. In this study, large-scale field tests are carried out. There are areas with an excavation depth of 10m or more, but some errors have occurred in calculating the soil volume by uniformly applying the soil conversion factor for a depth of 1 to 2 m. According to the field tests, the earthwork volumes applied with the soil conversion factor for each depth increase by 3.9 to 9.4% compared to the soil volume applied uniformly with that of 2 m depth.

The purpose of this study is to establish the central hierarchy and urban spatial structure of Daejeon in 2040 using differentiated analysis indicators. In order to establish a central hierarchy in the future urban space of Daejeon City, three indicators were derived: population density, use of buildings (commercial, office, residential, etc.) and traffic volume data(KTDB). The results of analyzing the center hierarchy using indicators are as follows. First, the primary centers responsible for urban (core) functions are set in three areas, including Dunsan downtown, the original downtown (Daejeon Station area, designated as a special urban convergence zone), and Doan New Town, and the secondary centers corresponding to sub-city centers (regional bases). was set at 9, 10 tertiary centers corresponding to regional centers (living area centers), and a center hierarchy was established with 5 new specialized bases. Second, new secondary and tertiary centers emerged that were different from the center hierarchy in the 2030 Daejeon Urban Basic Plan. The three indicators used in this study yielded meaningful results in establishing urban spatial structure and central hierarchy that can secure urban competitiveness.
